Developer Explanation: Midori Mihogawa's setting borrows the identity of the game's reporter, Minoru Mihogawa.
The production scope of the Canaan arc
When Ishiijirou completed the script for the main story of "428" and was preparing for filming, he commissioned TYPE-MOON to produce an extra story about Kanan. After Nasu was allowed to freely use the character, he placed it outside the main storyline; Ishii hopes to use fantasy to depict the chain of war and revenge, ultimately leaving behind a hopeful ending.
The hidden theme of this article
In his development review, Ishiijirou explained that "428" deliberately avoids sharing a common theme at the beginning, instead giving each of the five protagonists a different theme to temporarily hide the story's common theme.
Original planning and live production production
Ishii recalls that in 2006, candidates for SEGA-Chunsoft's joint project included live-action sound novels; After considering "Street 2," the producers shifted to the brand-new "428" set in Shibuya. The original van explosion scene underwent relocation adjustments: the plan before Pantheon was moved to Park Street due to the disappearance there, and the Apple Store front was moved to United Arrows due to the poor compositing of Morning Light Shadow. Ishii handed the script to Yasutaka Mouri to discuss the filming difficulties, and after each shoot, he imported and reviewed a large number of photos at night to avoid disrupting the on-set command.
Organize scripts and interfaces by time
The original development of "428" expanded the outline over time periods, then handed over to Kitajima Yukinori to rewrite, with the team gradually finalizing the setting through discussion. Ishii provides players with clear hints and flowcharts, and the game screen is reincarnated into a timeline, emphasizing the unity between the visuals and the timeline. When Kana enters the bad ending, the phone photo before 109 is replaced by a composite image by Koichi Nakamura; The director also pointed out that this supplementary drawing may still leave minor plot conflicts that make the pursuer stop chasing after them.
Casting choices and voice choices
For "428," when the outline was completed and the script was about halfway through, live-action actors were selected, focusing on working on site in Shibuya and showing strong visual appeal. The story focuses on a single day, so the team reduced the number of garments needed and enhanced quality with stylists and multiple brands. Ishii once tried to add voice actor voices to scenes, but felt the voices clashed with the photos and expressions, so she ultimately chose not to include the dialogue. The invitation for Akio Otsuka's Suzune arc live-action shoot was assisted by the agency, and his white outfit also echoed his Black Jack voice image; The plan to place related comics behind the desk was not adopted.
Music division and scene adjustments from the original Wii production
The music requirements for the original Wii "428" were passed on to Eiki Sakamoto through Kojiro Nakajima. "Mobilization" commissioned based on keywords and usage scenes, and the first submission was approved; A version of 'Tension' was also prepared without the piano, and the original version was used to reduce the obvious sense of recurrence.
"Upper Rank" was originally used for scenes involving different characters. Following a colleague's suggestion, Furuta reallocates the music and finds it suitable for Mihokawa's conversations with people; This adjustment makes the music choices for different characters more distinct.
The creative discussion for "Jishou" began with Nakajima bringing up Kecak to inspire Sakamoto, and Iino then poured strong voices into the Osawa arc, where the situation rapidly shifted.
The 2018 edition of the case was made public
A female college student's older sister was kidnapped, and the perpetrator demanded that she pay ransom in front of Shibuya Station during the day. As a rookie detective, Garner handles this case while also facing another incident where his fiancée's father comes to town and demands to see him.
Reporter Yu Houchuan Minoru received a plea from an old editor: gang lenders came to collect debts. He decided to step in and help, and soon got involved in major news.
2018 Edition Timeline and Choices
The stories of the five characters unfold in parallel, with a timeline that allows players to freely switch between characters, progressing through each one-hour interval. The choice of one character can have disastrous consequences for another; The official English website lists over 50 possible endings, encouraging exploration of different options.
